Important information

• Device selection
  You can select the device you are using, which means that the core, the default ddf file, and the flash loader (if available) are selected automatically. This is possible for all devices that are supported with header (.h) files and device definition (.ddf) files.

• Upgrade information

  • Before you install
    To avoid any problems, do not install the 6.x release in a directory where you have previously installed a 5.x, 4.x, 3.x or 2.x version of IAR Embedded Workbench for ARM.
    Either uninstall an earlier product, or install this release in a separate directory. However, as before, it is possible to install different products, all using version 6.x of the generic IDE component, in the same root directory.

  • Migrating your application
    If you are migrating from version 5.x, 4.x or 3.x to this version, we recommend that you read the ARM IAR Embedded Workbench Migration Guide.
    Additional general information can be found in the technical note 40394.
    Stacks are required to be aligned on 8-byte boundraries, additional information specific to stack alignment can be found in the technical note 96045.

  • New Freescale Kinetis part numbering scheme
    Version 6.30 and later implements the new Freescale Kinetis part numbering scheme. The following old device selections will be automatically converted to the new part numbering scheme:

    • K40Xxxx ⇒ MK40DX256Zxxx10
    • K53Xxxx ⇒ MK53DN512Zxxx10
    • K60Xxxx ⇒ MK60DN512Zxxx10
    Other devices must be manually converted.

• Using Cortex-R4 in big-endian mode
  When big-endian is selected for a Cortex-R4 core, the default big endian mode is BE32. The normal big endian mode for Cortex-R4 is BE8, so make sure that you select the correct mode for your target.

New features

• None.

Known Problems

• If the Memory window displays the middle of a selection that is larger than the Memory window and the formatting (1x, 2x ,4x) is changed, the Memory window scrolls to the bottom of the selection.
  [EW13204]

• IAR Embedded Workbench shortcut keys do not work in the Terminal I/O window.
  [EW14290]

• The Build message window might fail to scroll to the bottom when you build a project. This occurs for certain combinations of message line length and window width if a line must be wrapped. A simple workaround is to make the width of the IDE window larger or smaller.
  [EW15473]

• There is no vertical scroll bar in the left window when you split an editor window vertically.
  [EW15588]

• If the compiler optimization option Instruction scheduling was specified, it is lost when you convert a project from version 3.xx to 4.xx.
  [EW15605]

• You cannot select the last line in a file just by clicking on the line number. This is possible for all other lines.
  [EW15705]

• The read/modify/write operation on some NXP LPC I/O registers defined in the iolpcxxxx.h files might cause reading and writing of undefined bits.
  [EW16180]

• The IAR Embedded Workbench IDE postbuild action freezes when trying to run a GUI-based application.
  A workaround is to prepend the postbuild command line with: cmd /c.
  [EW18171]

• A missing debug driver GUI DLL (WTD) might cause a warning dialog box to appear every time a project is opened.
  [EW18350]

• If the IAR Embedded Workbench IDE window is minimized during flash download, the sizes of the subwindows change and become very small.
  [EW18642]

• The MS definition in tms470r1b1m_bit_definitions.h, conflicts with the MS definition in iotms470r1b1m.h.
  [EW18691]

• Moving an undocked window to another screen on a dual monitor system causes resizing problems.
  [EW19039]

• The IDE fails to expand $TARGET_BNAME$ when using it in the call of an external tool and the output file doesn't exist.
  [EW21158, EW21197]

• Directing the output from the output converter to a file with extension .out causes EWARM to hang.
  [EW21166]

• The TDGC peripheral is missing from the header and ddf files for the Atmel AT91SAM9263.
  [EW21551]

• The EWARM may crash with a protection fault, or display an empty workspace window, if ClearCase 7.1 is installed on the same computer. Read more in technical note 63639.
  [EW21945]

• The example projects for TI RDK-IDM do not work on Rev C16 boards.
  [EW21960]

• ctrl-v and ctrl-c have problems when used with the Online Help system. As a workaround you can use Copy and Paste from the context menu.
  [EW22313, EW23145]

• If output converter settings are changed in the IAR Embedded Workbench IDE, and the IDE is kept running, then an attempt to run IarBuild.exe will terminate silently with exit code 1.
  [EW22481]

• Sometimes the value of a float type placed in a packed struct is displayed incorrectly.
  [EW22529]

• A file corruption problem might cause dependency files (filename extension .dep) to describe some include files as files that generate output files (like, for example, .c and .cpp files). This will cause the IAR Embedded Workbench IDE to terminate unexpectedly when:
  - you perform a Find in Files search with the Project files and user include files option selected
  or
  - you choose the editor window context menu command Open file.h on an #include "file.h" line.
  [EW22792]

• If the Linker configuration file editor fails to modify a linker configuration file because it is read-only, this is not reported.
  [EW22817]

• If you have a network license and updates IAR Embedded Workbench from version 6.21 or older (6.20 or older in Japan), to version 6.30 or later (6.21 or later in Japan), then the license key might have to be re-entered in the installation wizard.
  [EW22831]

• On Windows XP, the clickable area for changing language is limited to the left half of the flag icon.
  [EW22976]

• The Cortex-M NVIC registers are missing from some debugger device descriptions.
  [EW23046]

• A trailing space in Project>Options...>General Options>Output>Output directories makes the linker terminate with an Internal Error.
  [EW23084]

• It is not possible to have two files in two different paths with the same name, in an EW project.
  [EW23217]

• If two header files in different paths in an EW project have the same name, then the wrong file might be opened when right-clicking on the name in the #include statement.
  [EW23233]

• If at least one element of a structure is of a type defined in stdint.h, and a specific structure variable is initialized or constant, then the auto completion might not work for that variable.
  [EW23312]

• If you have IAR Embedded Workbench IDE installed for several different tool chains in the same directory, the IDE might be in mixed languages if the tool chains are available in different languages.

• The Event log mechanism based on ITM is not supported when using the ST ST-LINK debug probe. Support will be added in the next update.

• IAR Embedded Workbench IDE - Known problems

Program Corrections

Version 6.40.2

• Reloaded editor files were incorrectly scrolled to the beginning. They are now opened at the expected location.
  [EW23252, EW23280]

• The editor no longer tries to identify special comments like //! or /// (e.g. Doxygen or javadoc comments). Now everything after // is handled as a normal C++ comment.
  [EW23264, EW23275]

• The Find/replace operation generated a sound for each replacement. Now a beep is emitted during a replace operation only when the document is read-only. [EW23265]

• The caret color is now set to white if the background is dark, and black otherwise.
  [EW23277, EW23291]

• The IDE could crash when a leaf was double clicked in the Code Coverage window, because of a missing path in the editor view. This has been corrected. [EW23283]

• The editor could become sluggish when operating on files located on a slow network drive. Speed has been improved by changing the behavior of file monitoring (i.e. detecting file changes made externally).
  [EW23284]

• Input via a non-Latin keyboard (e.g. Cyrillic) was not working. This has been corrected.
  [EW23323]

• The flash loader for Freescale MK61FN1M0xxx12 did not work.
  [EW23326, EW23203]

Version 6.40.1

• Editor line numbers exceeding 5 digits were partly displayed outside the line number column. This has been corrected.
  [EW21642]

• Printing a multipage selection in the editor window that did not start at the begining of a line and/or end at the end of a line could fail to print all selected content. This has been corrected.
  [EW21961]

• The source browser could cause the IDE to become unresponsive if the license for the compiler could not be verified. This no longer occurs.
  [EW22350, EW22499]

• The context menu command Go to definition could fail if the function was defined in a header file. This has been corrected.
  [EW22518, EW22612]

• Having a shift-left operator within a macro definition, as in:
  #define RUN_LED 1<<10
  caused a number of functions following such a definition to be omitted from the editor Go to Function window. This has been corrected.
  [EW22809]

• The following construction:

  #define INCLUDE 
  #include INCLUDE
  int main(void)
  { 
    ......
  

  could cause the source browser to miss the definition of main. This no longer happens.
  [EW22948]

• A failed post-build step was not included in the error count displayed in the status bar. This has been corrected.
  [EW23110]

• Setting the editor font to "Terminal" resulted in "Courier" instead. This has been corrected.
  [EW23156]

• IAR Embedded Workbench IDE - Corrected problems

User guide corrections

• None.

Miscellaneous

Adding device support
A set of documents is available that describes how to add additional device support to IAR Embedded Workbench for ARM.



Document	Description	Template
Flash loader
Device header format
DDF format

Running GUI-based programs from the project manager custom build rules
To run a GUI-based program from a custom build rule, the program must be wrapped with cmd /c, for example:
cmd /c prog.exe $PROJ_PATH$.

Adding the paths of project header files to the build
To activate this feature, add the special variable $PATHS_OF_PROJECT_HEADER_FILES$ on the Extra options page in the C/C++ compiler category of the Project Options dialog. The result is that the directory path of each member header file in the project is added to the command line using the -I command line option. For example, if the project contains the header files C:/a/fa.h and C:/b/fb.h, the compiler command line will get the additional arguments -IC:/a/ and -IC:/b/.

• ITM event plot function in timeline window
  The Timeline window has been enhanced with a graphical event log for Cortex-M3/M4 users. To aid in analyzing the behavior of your code, place predifined macro functions at places of interest in the code, and when these points are reached during execution, event messages will be sent and appear in the Timeline window. The plotted events can be correlated with the source code, detailed context timing is also provided.

• Function exclude mechanism in profiler
  The function profiling window has been enhanced with a function hide mechanism. Functions that are not of interest can be filtered out. This can be useful when working with an RTOS, RTOS kernel functions can be filtered out, to get a focused picture of where the execution time is spent in the actual application code.

• Support for Texas Instruments Stellaris ICDI (new in 6.21.3)

New features

• Power debugging
  Power debugging is a methodology that provides software developers with information about how the software implementation in an embedded system affects system level power consumption. By coupling source code to power consumption, testing and tuning for power optimization is enabled. The debug probe samples the momentary current drawn by the system and feeds it to the debugger where the measured current is synchronized with time stamped program counter values. This allows the debugger to present power consumption directly correlated to the source code. The debugger supports power data from the following sources:

  • J-Link Ultra
    Power data is measured with high accuracy at the board level. A future adapter will be available in Q2 2011 to measure power at the MCU level. Supports calibration.
  • J-Link
    Power data is measured with low accuracy at the board level. Does not support calibration.
  • The Energy Micro EFM32 Gecko development and starter kits
    They have a J-Link compatible debug probe integrated on-board. Power data is measured with high accuracy at the MCU level. Does not need calibration.
  Power data can be visualized as a power log, a graph on a time scale, or in the function profiler as energy consumption.
  More information can be found in IAR Embedded Workbench® C-SPY Debugging Guide
